I have a question regarding UART controller. Is UART controller a general name? I mean that if we use RS-232 protocol, we should name this UART controller, RS-232 controller and if we use RS-485 as protocol, we should call this UART controller, a RS-485 controller and so on? I've noticed that we generally say network controller (protocols:Ethernet, token ring,ATM.) and if the protocol implemented is Ethernet for example, we say Ethernet controller. Is it a correct comparison between UART controller and Network controller meaing that they both are general names? Thanks a lot for your clarifications. New Home 656a Manual Meat more.

What are all of these and how do they relate to each other? - Electrical Engineering Stack Exchange • Serial Programming/Typical RS232 Hardware Configuration - Wikibooks, open books for an open world Serial is an umbrella word for all that is 'Time Division Multiplexed', to use an expensive term.

It means that the data is sent spread over time, most often one single bit after another. All the protocols you're naming are serial protocols. UART, for Universal Asynchronous Receiver Transmitter, is one of the most used serial protocols. It's almost as old as I am, and very simple.

Most controllers have a hardware UART on board. Besanko Microeconomics. It uses a single data line for transmitting and one for receiving data. Tomtom Karte Central Europe Download Movies there. Most often 8-bit data is transferred, as follows: 1 start bit, low level, 8 data bits, 1 stop bit, high level. The low level start bit and high level stop bit mean that there's always a high to low transition to start the communication. That's what describes UART. No voltage level, so you can have it at 3.3 V or 5 V, whichever your microcontroller uses.
